Claims. (01. sis-55.1)

out of! a piece of the same; furthermore to stuff or load the said pieceand to crimp the ends of the piece to hold a disc of similar material enclosed upon the contents. The primary object therefore of such amechanical assemblage is to provide an inexpensive method for theforming, loading and closing of containers to hold surgical dressings,lint, gauze, etc, condiments, etc.; tobacco or any other dry or semi-dryproducts, chiefly dehydrated vegetable i'oods to meet the prevailingcivil and military conditions now confronting the Nation.

As dehydrated foods must not be crushed or pulverized, a special methodof packing and a special container must be employed, and so far as I amaware no such container has been provided. A container of this type tobe used with this and made by this machine may be found disclosed in mycopending application, Serial No. 472,640 filed January 16, 1943.

Other objects will appear in the following specincation and claims andthe subjoined drawings forming a disclosure of my invention. 1

in elevation, showing the related position of. the matrix, cross head,guides, crimper yokes and the cylinder to activate the matrix.

Figure 511s a top plan view of the matrix, partly in section, withfragmentary view of location of the crimping means.

Reference now being had to the numerals, as follows: In Fig. 1 the bedplate i is supported by legs 2. Mounted on the bed plate i at one end isa compression cylinder 4 having a piston therein t and connected to thetubular piston rod 5, and bearing against a compression s ring 6,visible in Fig. 2. The forward end of the cylinder 6 is provided with aconical head-yoke l, serving to guide the tubular rod 5, and adapted tohouse the travel, the spring 6 serving to return the piston 3 and rod 5to initial position as shown when the fluid pressure is'relieved.

The fluid pressure referred to is fedthrough a pipe 8, and the releaseof pressure is handled through the same. The pipe 8 is connected throughthe cutout cock 8, tov main reservoir l0 and the same is .connectedto anair compressor and motor hereinafter fullyde'scribed. V

Mounted upon one end of the bed plate as before stated is the compr ioncylinder 4, having a piston 3, see Fig. 2, and a hollow tubular rod 5;and mounted upon the opposite end of the bed plate is a pair ofguides'designated i3 and Ba, see Fig. 4, adapted to secure a matrix M ina slidable mounted position. The matrix is thus slid by means of apiston rod l5 and complementary piston l5a working in a cylinder i6.

Disposed parallel to the bed plate and superimposed thereto, are theguides Ill and Na, connecting the compression cylinder it and the matrix'guides i3 and i311 of the matrix assemblage It, for vertical shift. Theguides ii and Ma have a for lateral shift. The said cross head it isprovided with a split collar 119, Fig. 2, and lever and screw N to clampthe cross head it to the-tubular hollow cylinder rod .5 as,-when and ifrequired.

Thus the cross head may be manipulated or handled by the fluid pressureto compensate for different types of operation of loading and closingcontainers. 7

The cross head it is provided with a ramrod 59A mounted thereon for stgthe tubular sections cut off and reposing within the matrix it. Mountedon the matrix guides it and Ba are crimping means 2t and Ella carried byyokes 2i and Zia secured to the guides it and lie. These crimping meansare adapted to seal the ends of the tubular section after loading andwhile it is in the matrix it.

In Figure 2, a cross section of the matrix is shown with the sequence ofoperation above noted. The matrix it is provided with a series ofapertures and in sequence of the vertical rise, the tubes reposing inthe said apertures in 23, the tube 22?; is just cut oil, loaded andstufied in 23a, and crimped in 23b. The hollow piston rod 5 extendsforward and rearward of the piston 3, the rearward portion extendingthrough a fluid pressure stumng box 24, having a chuck 25.which isprovided with slidable grip pins 25 and 26a adapted to grip the tubularstock and facilitate the rotary movement of the same, tubular stock usedwith spring t, when piston is forced the full length of comfortable easysliding fit within the matrix It and apertures 28, to compensate forswelling under pressure when loaded, and to prevent undue tightness, toforbid easy discharge from the aperture of the matrix. a

Figure 3 shows the cutoff wheel mechanism 21 adapted to sever thetubular stock 22 when in position within the apertures of the matrix l4.

This is accomplished by manual rotation of the tube stock gripped by thechuck assemblage 25, and pins 20 and 26a of the invention;

Figure 4 shows the inside view of the elevation mounted on guides l1 andIIa is shown in section,

the crimper yoke 2| flxed to guide frame it and Ila by means of dowels28 and 28a.

der n. activating the pistm Ila and its M II and moving upward thematrix H.

As the matrix l4 moves up or down. notches- 24 shown in dotted lines,Fig. 5, insure registry of the apertures of the matrix with the rod I,the ram rod "a and the crimpers, by providing seats for the registeringrod 4|. Rod 4| is seated by spring 48 and retracted by air pressureacting on piston 42 in cylinder 48. Air enters the space 41 to theleftof the piston 42 from pipe 44 (Fig. 1) through port 45. The rammingpressure in cylinder 4 is regulated to suit the material to be packed,being for example, high for surgical dressings, low for dehydratedfoods.

To prevent displacement of matrix while loading, pressure is relieved byexhaust through cock 88, thus diminishing pressure in cylinder I. andallowing the matrix l4 to remain securely locked. To unlock the matrixl4. a return of full feed of fluid pressure passes through the weightedcheck valve 4| into the cylinder II, this flow being more rapid than thebranch pipe locking The tool comprises a crimper carried by the yoke 2|provided with a threaded shank 2O having a hand wheel 30 to actuate thesame, the

opposite end of the shanktl'being a smooth taper broach, having a pin 82rotatably mounted transversely thereof and piercing the same. The p n 32is provided with grooves 33 and 33a conforming to and meeting the verysame or flush opposite end engages the inner walls of the tube stock 22,and the rotary movement andadvance causes the grooves 32 and 22a to engae the ends of the tube stock and bend them inwardly to conform to thetaper broach, thus ironing the ends inwardly and serving to close thesame against the predisposed wads, disks or fitting, by crimpinginwardly the ends of the said tubular stock. The automatic look, asshown in Figure 5, is hereafter more fully-described to secure thematrix l4 in different positions of shifted adjustment.

The operation of the assemblage is as follows:

Ordinary paper tubing or other suitable material 22 of conventionalmanufacture and design is inserted through the chuck and the piston rod5 to confront one of'the apertures of the matrix l4. This material iscut off by holding the cutoil' wheel 21 in contact with the tube bymanual control, meanwhile rotating the chuck wheel 25. Compressed airadvance the piston rod 5 to make the contact and feed the tube in theaperture. Releaseof compressed air, ex austed through pipe 22, thentrapped behind the piston 3 in cylinder 4, allows the compression of thespring 8 to return the piston and rod to initial position as shown inFigure 2.

Thus the operation in sequence is a follows: Mounted in a convenientplace upon the bed plate I is an electric motor 12, coupled by a belt 34to an air compressor 35, air from the compressor as led by a pipe 38 tothe reservoir designated l0, thence through pipe 8, through the threeway cock 9 to control the fluid pressure, to activate either piston andcylinder designated 4 and 5 or I 5 and I! respectively.

Fluid pressure is passed either by exhaust or trapped air, in cylinder 4through train pipe 31, closing check'valve is and opening springweighted check valve 40, and passing into cylinmeans of piston and rod42 and 42, but as the pressure'builds up and backs through the branchpipe and through port 45 in the housing cylinder 48 of the same, thisback pressure bearing against piston 41 in the cylinder counteracts theauto- ,matic compression of the spring 43 and withdraws the piston fromthe notch and unlocks the matrix l4,-al1owing it to move to nextposition where it is checked, and retarded by a manual reduction inpressure as before stated.

By slight exhaust and relief of pressure through the port 40a of thethree way cock 38 the trapped fluid is released through check flap valve39 and exhausted; thus, the matrix remains locked until the piston 42 isdisplaced by the building up of back pressure to counteract thecompression of the spring 43 of the lock mechanism. Thus in sequence ofrise and fall of the matrix l4, the same is securely and preciselylocked for the uses and purposes named. In Figure 2, the matrix M withaperture 22b is shown in crimped position of the tube section ofcontainer,
